Utility locations in rootfs config - PetaLinux-2019.2

[jk_29]

Hey guys,

Where in the rootfs config menu can I enable 'pgrep', 'pkill' and 'fsync'. I think these used to come in busybox but the version has changed.

Side note, if anyone is looking for a complete 'dd' implementation or 'base64', they are enabled using: Filesystem Packages -> misc -> coreutils

Thanks,
Joel

I'm also looking for pkill (but in 2019.1).  Any luck finding it?

My side note, I was also looking for ipcs which I found in util-linux.

Thanks,

Hey Steve! Glad I am not the only one. No luck yet, will let you know if I find it on my own!

In case you haven't located them, procps and pkill are in the procps package (Filesystem packages -> base -> procps).

Note that many of these utilities can also be provided by busybox (at a fraction of the size of their "full" size versions). You can run "petalinux-config -c busybox" to tweak which utilities are included into busybox. This does appear to include "fsync" as an option.

Thank you very much!
Looking at procps, seems to be exactly what I need for the process utilities.
I was unaware we could configure busybox directly. Unfortunately I seem to be hitting another bug there (https://forums.xilinx.com/t5/Embedded-Linux/Failed-to-config-busybox/td-p/1092560) but I am sure that it will do the trick once I get the config up and running. Thanks again!

Thanks!

I found I pgrep and pkill in the util-linux-dev package but, unfortunately, configuring that in doubles the size of our image which is not good.  I may try configuring in just procps but I believe I did that previously and did not find pkill in the resulting image.  But I may be wrong on that.

In any event I wasn't aware that I could configure busybox, that's a great tidbit to know.  I'm always a little wary of the busybox utilities since they sometimes don't provide all of the necessary functionality (nc comes to mind).  But in the case of this set of utilities I have hope that the busybox versions are adequate.  And the good news is that they have minimal impact on image size.
